You can always pump more. Its a supply and demand kind of thing. Pump for a few minutes after milk stops coming out and it should tell your body to produce more.
Well kus its soo hard to latch him im jus pumping I use a nipple shield to latch him at times but when I put him on my boob he whines
Are you just exclusively pumping or breastfeeding as well?
thats normal..coz thats the point when you feed him colostrum.. eventually after a while, it'll be easier..if youre having issues producing milk, try looking for moringa capsules.. and drink lots of water.. and always add some soup in your meals..i breastfed with my first and will be doing the same this time..
